Distortion when switching to/from landscape mode

[Mercury]

Issue

When switching from landscape to portrait, or from portrait to landscape, the screen temporarily shows a distorted image. Chances are the orientation swap happens slightly before/after the change to the video buffer. (Portrait to inverted portrait, or landscape to inverted landscape does not have the same problem)

Perhaps the screen should be blacked out (or some other uniform color) or the backlight should be temporarily shut off during the orientation swap.

Reproducing

1) Install the accelerometer gestures and screen orientation software as instructed here: ​http://wiki.openmoko.org/wiki/Gestures Or use the xrandr command to change screen orientation manually.
2) Rotate the orientation of the display.

yes if you do xrandr -o 1 then xrandr -o 3 with the latest xglamo it will go wrong, there is a ticket for this but I don't remember which. other then that, if you always xrandr -o 0 between each operation, it works fine for me. close as duplicated.
